CS5374 Description
The CS5374 bines two marine seismic analog measurement channels into one 7 mm x 7 mm QFN package. Each measurement channel consists of a high input impedance programmable gain differential amplifier that buffers analog signals into a high-performance, fourth-order ΔΣ modulator. The low-noise ΔΣ modulator converts the analog signal into a one-bit serial bit stream suitable for the CS5376A digital filter.
